Episode 10: Tim Rault-Smith - Lessons in Startup Problem-Solving and Scaling Innovation

Logo of Adopter - the marketing agency for deep tech and climate adaptation.

Tim Rault-Smith, startup advisor and board member at SALINE Ventures, discusses startup scaling, product-market fit, and the realities of early-stage company building on Episode 10 of Scaling Green Tech, a podcast by Adopter.

Rault-Smith draws on his experience as one of ForgeRock's earliest employees - a digital identity and access management company that grew from a distributed team of around 12 people to an IPO on the New York Stock Exchange in 2021, before being acquired by Ping Identity in 2023. He traces how ForgeRock started with no products of its own, relying on services revenue and early equity grants to hold the team together. He connects those lessons to his current work advising EV and clean energy companies, using 3ti and nodum as live case studies in how founders can test demand and sequence their route to product.

This episode is relevant for deep tech and EV founders at early and growth stages, startup advisors, angel and venture investors, and operators in EV charging infrastructure who are navigating product-market fit, capital raising, and the transition from services to product business models.

Guest Profile

Tim Rault-Smith is a startup advisor and board member at Saline Ventures, specialising in the EV and charging sector. He spent the early part of his career at Sun Microsystems and later at ForgeRock, where he joined as one of the company's earliest employees and served as VP across technology services for six years. His background spans technical support, sales engineering, and identity and access management (IAM) - fields he worked in from the late 1990s onwards.

Saline Ventures is a business development partner focused primarily on privately owned companies with strong products that need commercial support to grow. Founded with a philosophy of providing external BD resource to companies that lack it in-house, Saline has extended this model to work with earlier-stage startups in sectors including EV and clean energy.

Key Takeaways

  • Founders routinely mistake interest for sales. A potential customer saying "that's interesting" is not validation. The right signal is a customer who can articulate how the product affects their bottom line and is willing to commit money to it.
  • Selling before you build is a legitimate strategy, not a shortcut. If you can demonstrate enough of a solution to get a pre-sale or early commitment, you have validated demand without the risk of building something nobody wants.
  • Every company is defined by where its revenue comes from, not what it calls itself. A company with a great product but service-dominated revenue is a services company. Founders should be honest about this distinction early, because it shapes hiring, investment strategy, and growth ceiling.
  • Starting as a services company is not a failure mode. It can generate early revenue, reduce capital dependency, and force commercial discipline - all of which make the eventual transition to product more sustainable.
  • Taking on too much capital before achieving product-market fit is one of the most common ways startups fail. Once the money is spent and the cap table is loaded, a pivot becomes structurally very difficult to fund.
  • Founders should do due diligence on their investors with the same rigour investors apply to them. Knowing where the money is coming from, whether it is actually available, and what strings are attached is not optional - it is a survival question.
  • Commitment in a startup is not just about hours. It is about understanding that the boundaries between work and personal life will be harder to maintain than in a corporate role, and being genuinely prepared for that before you start.

FAQs

  1. What is product-market fit and how do you know when you have it?

Product-market fit is the point at which a product demonstrably solves a problem that a defined set of customers will actually pay to fix. Rault-Smith draws the distinction between interest and fit clearly: a potential customer saying "that's interesting, I can imagine someone using it" is not product-market fit. A customer saying "that would affect my bottom line and I would buy it" is. Most founders undertest this. They build first and discover the gap later - often after significant capital has been spent.

  1. Should founders try to sell before they've built their product?

Rault-Smith's view is yes, where possible. If you can describe a solution clearly enough to get a commitment or a pre-sale, that is more valuable than any internal conviction about the product's quality. It validates that a real buyer exists, surfaces what the buyer actually needs, and reduces the risk of building something the market won't take. Not every product allows for this - but founders should default to testing demand before assuming it.

  1. What is the difference between a services company and a product company, and why does it matter?

A services company sells time or the delivery of a service; its revenue is directly tied to capacity. A product company sells something that can scale beyond headcount. Rault-Smith argues that founders need to be honest about which one they actually are - because the answer comes from where the revenue comes from, not from what they call themselves. Starting as a services company is not a problem. It can generate early revenue and reduce capital dependency. But it creates a ceiling, and founders who don't recognise that early will eventually hit it.

  1. When should a startup raise venture capital?

Rault-Smith's position is that raising significant capital before achieving product-market fit is one of the most common ways startups fail. Once investment is spent without generating product and revenue, the cap table becomes a structural barrier - earlier investors are sitting on paper expectations, and new investors are being asked to fund a company that is effectively starting over. The stronger position is to generate some early revenue first, even from services, before taking on substantial external capital.

  1. How should founders approach due diligence on investors?

Founders should apply the same rigour to investors that investors apply to them. This means confirming the capital actually exists, understanding the investor's motivations, and scrutinising any exclusivity clauses before signing. Rault-Smith's view is that the strings attached to money are as important as the money itself. Institutional investors often want board seats. Some will require exclusivity during a raise. Founders who don't interrogate these terms early can find themselves locked out of alternatives at exactly the point they need them most.

  1. How much commitment does an early-stage startup actually require?

More than most people expect, and more than most job descriptions convey. Rault-Smith is direct about this: a clean boundary between work and personal life is genuinely difficult to maintain in an early-stage startup, particularly one with international customers. His view is not that founders should sacrifice everything, but that they should be honest with themselves and their teams about what the role actually involves before they commit. Misaligned expectations on commitment - within a founding team especially - create friction that compounds quickly.
